## XML attributes

### android:layout_gravity

Standard gravity constant that a child supplies to its parent. Defines how the child view should be positioned, on both the X and Y axes, within its enclosing layout.

Must be one or more (separated by '|') of the following constant values.

Constant | Value | Description
--- | --- | ---
bottom | 50 | Push object to the bottom of its container, not changing its size.
center | 11 | Place the object in the center of its container in both the vertical and horizontal axis, not changing its size.
center_horizontal | 1 | Place object in the horizontal center of its container, not changing its size.
center_vertical | 10 | Place object in the vertical center of its container, not changing its size.
clip_horizontal | 8 | Additional option that can be set to have the left and/or right edges of the child clipped to its container's bounds. The clip will be based on the horizontal gravity: a left gravity will clip the right edge, a right gravity will clip the left edge, and neither will clip both edges.
clip_vertical | 80 | Additional option that can be set to have the top and/or bottom edges of the child clipped to its container's bounds. The clip will be based on the vertical gravity: a top gravity will clip the bottom edge, a bottom gravity will clip the top edge, and neither will clip both edges.
end | 800005 | Push object to the end of its container, not changing its size.
fill | 77 | Grow the horizontal and vertical size of the object if needed so it completely fills its container.
fill_horizontal | 7 | Grow the horizontal size of the object if needed so it completely fills its container.
fill_vertical | 70 | Grow the vertical size of the object if needed so it completely fills its container.
left | 3 | Push object to the left of its container, not changing its size.
right | 5 | Push object to the right of its container, not changing its size.
start | 800003 | Push object to the beginning of its container, not changing its size.
top | 30 | Push object to the top of its container, not changing its size.

## Constants

### UNSPECIFIED_GRAVITY

    public static final int UNSPECIFIED_GRAVITY

Value for `gravity` indicating that a gravity has not been explicitly specified.

Constant Value: -1 (0xffffffff)

## Fields

### gravity

    public int gravity

The gravity to apply with the View to which these layout parameters are associated.

The default value is `UNSPECIFIED_GRAVITY`, which is treated by FrameLayout as `Gravity.TOP | Gravity.START`.

- `Gravity`

## Public constructors

Creates a new set of layout parameters with the specified width, height and weight.

Parameters
`width` | `int`: the width, either `ViewGroup.LayoutParams.MATCH_PARENT`, `ViewGroup.LayoutParams.WRAP_CONTENT` or a fixed size in pixels
